Abstract:
Multibeam bathymetry raw data was recorded in the North Atlantic during cruise M175 that took place between 2021-06-02 and 2021-06-28. The data was collected using the ship's own Kongsberg EM 122. Sound velocity profiles (SVP) were applied on the data for calibration. Please see environmental data (zip file) and the cruise report for details. The data was collected along the Oceanographer Transform Fault as part of an integrated geophysical and geological effort to re-investigate the role of large oceanic transform faults on the evolution of the ocean crust and lithosphere. Other data types collected during the cruise comprise passive earthquake detection using ocean bottom seismometers, and geological sampling. The bathymetric data set complements the one obtained during the M170 cruise to an overlapping area.
